The use of VMW has no particular drawbacks other than what Jochen said,
but I don't think it is a good solution:
all the sw is usually installed on a linux box by the package manager of 
the system (for debian apt-get, for red hat yum and so on) from a pakage 
(.deb, .rpm, ..) with just a command. It will be nice to have such a 
linux package of each perfsonar service.
Moreover, in this case, the upgrade of the sw to a new release will be 
very easy.
